Call 91101
Which signs mean call 911 right away?
Sudden numbness or weakness in the face, arm or leg, sudden confusion or trouble speaking, sudden trouble seeing or walking, or a sudden severe headache.
That is the CDC list of stroke signs, and CDC says to call 9-1-1 right away if you or someone else has any of them 1. Do not drive yourself, and do not wait to see if it passes. Numbness on one side is not a reason to try a capsule. Note the time the signs began, because it matters to treatment.
- Sudden weakness, a drooping face or trouble speakingCall 911. These are stroke signs, and every minute counts. Do not drive yourself. 1
- Weakness that spreads over hours or daysGet urgent care. Fast-spreading weakness can be Guillain-Barre syndrome, which is treated in hospital. 2
- A numb foot with a sore that will not healSee a clinician promptly, especially with diabetes. Feet that cannot feel can hide cuts that get infected. 3
- Shaky, sweaty, confused or faintPossible low blood sugar, which alpha lipoic acid can add to when you take diabetes medicine. Treat it as an emergency if severe. 4
- Yellow skin or eyes, dark urine, belly painPossible liver trouble. Liver injury has been reported with high-absorption turmeric products. Stop and call a clinician. 5
- Unusual bruising or bleedingTurmeric, CoQ10 and L-carnitine can matter with blood thinners. Call your prescriber. 6
- Chest pain, trouble breathing, swelling of lips or faceCall 911. Possible heart problem or allergic reaction. 7
This list is not complete, and a supplement is never a reason to wait.
Fast weakness02
What about weakness that spreads over hours or days?
Get urgent care. Fast-spreading weakness can be Guillain-Barre syndrome.
NINDS describes Guillain-Barre syndrome as an immune attack on nerves that causes weakness, sometimes severe enough to affect breathing, and says people are usually admitted to hospital 2. It is rare, and the point is not to diagnose it yourself. It is that weakness spreading up the legs or arms over hours or days is a reason to be seen the same day.

Foot sores04
Why does a numb foot with a sore need prompt care?
Because you may not feel the injury, and untreated sores can become infections.
NIDDK says nerve damage can make you lose feeling in your feet, so you may not feel a pebble in a sock or a blister, which can lead to cuts, sores and infection, and poor blood flow makes sores heal slowly 3. The NHS lists a foot cut or ulcer that is not healing among the early signs to see a doctor about 8. People with diabetes should check their feet every day and report any sore, even a small one.
Prepare05
How can you prepare before anything happens?
A little planning turns a frightening moment into a quick call.
Keep a medicine list on your phone
Include doses, allergies and every supplement, such as a nerve capsule. Responders ask for it first.
Tell someone you live with the warning signs
A second person often spots a drooping face or slurred speech before you do.
Know the time rule
When signs begin, note the clock time. Treatment choices can depend on how long ago they started.
Keep the bottle and the order email together
The lot code on the bottle helps if a reaction needs reporting later.
None of this replaces a clinician. It simply makes the first ten minutes of an emergency easier for everyone involved.

What if you have diabetes and feel shaky or confused?
Low blood sugar can look like a nerve problem, and it needs fast action.
Shaking, sweating, sudden hunger, confusion and fainting can all come from low blood sugar in someone who takes insulin or certain diabetes medicines. Follow the plan your own clinician gave you for lows, and call 911 if the person cannot swallow, cannot be woken or is very confused. Alpha lipoic acid, one of the six names in Flow Nerves, can lower blood sugar, so anyone on diabetes medicine should speak to a pharmacist before starting it 4. Do not add or skip a diabetes medicine because of a supplement.
Living alone07
What about older adults and people who live alone?
They benefit most from a plan, because nobody may be nearby to notice a change.
If you live alone, keep a phone within reach, tell a neighbor or relative the warning signs, and consider a check-in routine. Sudden numbness, a drooping face or slurred speech should lead to a call to 911 before anything else, even if the signs seem to fade. Fading signs can still mean a serious event, and the CDC list does not carry an exception for signs that pass 1. Speak to your clinician about any dizziness, falls or night-time foot pain that keeps returning, since those are common reasons for a review of medicines and supplements.
Afterward08
What happens after an emergency?
Follow-up with a clinician decides whether a supplement has any place at all.
After a serious event, the care team sets a plan, and every medicine and supplement on your list is reviewed. Ask directly whether a nerve capsule fits that plan, and accept the answer. If the answer is no, that settles it. Reading about a product never outranks the advice of the team that examined you.
Supplements09
Is there any role for a supplement in an emergency?
No. Supplements are slow and mild at best, and an emergency is neither.
Do not take an extra capsule, wait for a capsule to work or look up a product while you have these signs. Call for help first. If you are with someone who has the signs, stay with them, note the time, and tell the responders every medicine and supplement they take, including any capsule such as Flow Nerves. Keep the bottle where you can hand it over.

FAQ10
Flow Nerves questions people ask
When should I call 911 for numbness?
For sudden numbness or weakness in the face, arm or leg, sudden confusion or trouble speaking or seeing, or a sudden severe headache. CDC says to call right away.
Is tingling in the hands an emergency?
Not usually on its own, but sudden tingling with weakness, a drooping face or trouble speaking is. When unsure, call.
Can Flow Nerves treat a stroke?
No. It is a dietary supplement, not a drug, and it cannot treat any emergency.
What is Guillain-Barre syndrome?
An immune attack on nerves that causes weakness that can spread over hours or days. It is treated in hospital.
Can a pinched nerve be an emergency?
Usually not, but sudden loss of bladder or bowel control, or fast-worsening leg weakness, needs urgent care.
Is a foot sore really urgent?
If you cannot feel the foot, yes, see a clinician promptly, because infections can start unnoticed.
Should I take my supplements to the hospital?
Bring the bottles or a list. Responders need to know every medicine and supplement you take.
